Our regular customers know that Mytee Products carries heavy-duty bungee straps made with 100% EPDM rubber. They also know that EPDM bungee straps are ideal for flatbed trucking, where straps are expected to withstand a tremendous amount of punishment day in and day out. In light of that, we want to use this post to point out that your choice of bungee straps really does matter. As a truck driver, it would be a good idea to choose a bungee strap that is appropriate for the kind of work do.
There are basically three kinds of bungee straps you can buy:
• Natural rubber
• EPDM rubber
• Nylon wrapped rubber.
The first two options were detailed in a Mytee Products blog post a while back. At the time we excluded the Nylon wrapped rubber. We feel it is time to include that third option now that it is more readily available at DIY stores.
Natural vs. EPDM Rubber
When Charles Goodyear first developed vulcanized rubber in the mid-19th century, it revolutionized the way natural rubber would be used for industrial and manufacturing purposes. His vulcanization process led to the development of rubber car tires along with an extensive list of utilitarian items such as hoses, gaskets, and belts. Natural, vulcanized rubber was critical to the war effort in World War II as well.
As a material for bungee cords, natural rubber is strong and fairly resilient. It holds up well in most kinds of weather with the exception of excessive heat. High temperatures and direct sunlight can cause natural rubber to lose some of its elasticity.
EPDM rubber is a synthetic product that was created to make up for the severe shortage of rubber during World War II. It proved to be a better material for a lot of different uses, and it is the predominant form of rubber used today. Most of the bungee straps truckers use are EPDM rubber.
The strength of the EPDM is that it holds up exceptionally well in hot temperatures and under direct sunlight. But unlike natural rubber, it does not do well in extremely cold temperatures. Cold EPDM is prone to getting brittle and breaking or tearing.
Nylon Wrapped Rubber
Nylon wrapped rubber bungee cords are those cords you see being sold in different colors. Some are red, others are blue, and still others are yellow or green. The most important thing you need to know about these bungee cords is that they are not suitable for the trucking industry. They are intended primarily for light-duty use.
Campers and hikers love nylon wrapped rubber because it is very flexible and easy-to-use. It is great for securing a camping tarp or attaching a sleeping bag to a backpack. However, nylon wrapped rubber is not sufficient for holding down truck tarps at speeds approaching 60 mph.
You should also know that nylon wrapped rubber is not nearly as thick and it has a significantly lower tensile strength. Attempting to secure truck tarps with these kinds of bungee cords is asking for trouble. Do not use them for anything other than light-duty applications not involving cargo control.
We Have Bungee Straps and Rope
The good news for Mytee Products customers is that we have all the EPDM bungee straps and rope you need. You don’t have to go anywhere else to keep your truck well-stocked. You can buy bungee straps in packs of 50, with or without crimped hooks. We also carry rubber rope hooks ideal for drivers who want to construct their own bungee ropes when more length is required.
